4To the under side of thel guides KK are ner ends of the bars L L are so constructed and arranged that, as the `rods I I move for ward and` back, the said bars LL will be tripped by projections N N, to release, the levers M M at the proper time. The-projections n N N are ttedwith adjustable screws, asshown in FigLl. n v "The levers `M M are mounted on countershafts O"O on the outside ofthe frame, and

to their upper ends are attached adjustable connections 15 15, each secured to the ends of a spring, 14, extending across the loom, and made of vulcanized rubber or of spiral wire,

`sothat as the lower ends of the levers are al! ternately released `from `the `catches. L L, the

spring will cause the double lever P P' to be, suddenly retracted, and with sufficient force: i

to throwthe shuttle om end to end.

l On the opposite end of the counter-shaftsV O O are fastened the levers P I), to the upper endsv of, which are attached the arms P F.

The outer ends of the arms P 1?` arera'ttached` l to the` under sides of the shuttle-driver or picker R, that moves in the shuttle-bon S'.

` Within the shuttle-box S are hinged, on each side, metal plates s s, as shown in Fig. j 4, so that the free'ends of each plate may be v l forced, by means of a spring, toward the cenj. ter of the shuttle-box, for the purpose ofre` i tarding and retaining the shuttle as it nears the` limit of the throw. Theplates s sare adjusted, by means of set-screws t', to project4 more or less, as required, as shown in Figs. 4j' `and5.

For `the' purpose of opening orretracting` the plates s s, to release the shuttle for the return movement, vI employ a wedge, d., (shown in Fig. 5,) which is caused to' moveforward and force apart'the 'slides afa', (see Figs. 4l

and 5,)'which pass through the sides fof the shuttle-box, turning up at right angles, and are attached by set-screws to the adjustable supported in guides K K,attached to `each3 t,are inclosed in metallic tubes, on which hog- ,h y frames can be placed, if desired, so as to insure the requisite stiffness. The reedZ is supported at each end upon upright bars l l, Figs. 2 and 13, which move in vertical grooved guides in 'the sides of the frame A A.

friction-plates s s. The wedge d vis moved forwardl at the proper time by means of a short arm or lever, c, Figs. 4 and 5, operated by the jointed lever T, Figs. 1 and 2, mounted on the counter-shaft O, the lower end of which lever T is attached to a sleeve or collar, Tf,

Fig. 2, on the counter-shaft O; and on theun- 'der side of the said sleeve or collar is a projecting short arm, U, Fig. 2, through the lower end of which passes an adjustable setscrew, V, Fig. 1, the inner end of which is opposite a lug, e, Fig. 1, on the rods I l, so that j. spring, x, Fig. 1, on the sides of the frame A.

y y represent the front edges of the harnesses, which consist of horizontal metallic frames, in which are strung the hat metallic heddles on j wires extending lengthwise ofthe same.

Extending vback from each harness-frame are rods or bars f f, moving in guides in ther v. cross-tie B, as shown in Fig.3. To the rods f f are attached, in pairs, the levers. g g, se-

v cured at their lower ends to lugs 7c k on the i cross-tie D, and are provided with pins fitted ,with friction-rolls, that'move in cam-grooves h hf, Fig. 3, in `cam-wheels F F, mounted on l the main-shaft S, by vmeans of which an alternate reciprocating motion forward and back is imparted to the harnesses.

Z is the reed which beats up the woof or The longitudinal sides of the reed The lower ends of the bars l l are connected, by means of short arms n u, Figs. 3- and 7, to levers m m, so as to insure a free vertical motion to the said bars. The levers m m. are fulcrumed at m on l the inner sides of the frame, and are provided with pins tted with friction-rolls, that move i in the cam-grooves hlt in the cam-wheels E E on the shaft S, as shown in Figs. 2 and 7, soas to impart the requisite vertical motion -to the reed. 4 vThe take-up-will now be described: 2 is a roll covered with sandpaper,or other suitable frictional surface, as in common use, for tak'- ing up the cloth as fast as woven, and which' is wound on the bar A3, placed above roll 2, and iitted at the ends to move in grooves in the frame, so as to rise as it receives the cloth. v

On-.the end of the shaft which carries roll 2,

Vand outside the frame, is a disk, a", (see Fig.

2,) having an outwardly-projecting rim, r', and uponV the lportion of the lshaft which projects through the disk n are pivoted two arms, r r,

extending in opposite directions uponthe face of the disk u. i' The outer end' of each arm is beveled, as shown in Figs. 2 and 25, and between each end and the projecting rimr is placed a roll, 4, which is held in position by meansof ,a spring, 5, as shown 'in Fig. 2.

The rolls are further conned by means of a guard, c', attached to the arms r r; and the inclined orbeveled ends of the said arms, bearing against the rolls 4 4, cause the latter to` bear against the inner sides of the rim r and turn the disk n', with its shaft that carries the cloth, and release from the disk the friction when moved in the opposite directiomthe two arms acting alternately to move the disk. Connected to the arms 1' r are the long arms or bars p p, which are attached at their lower ends to a screw-pin, 3, passing through a slide,

t", fitted in a grooved cylindrical block, t, se-

necting by means of gears, two to one, so that either may be set in motion `or stopped atthe will of the operator.

Fig. 6 represents a shuttle adapted for the loom above described. vIt is composed of thin sheetsteel or other metal, withtwo parallel sides, 6 6, said sides being i'lat; or they may be slightly curved or corrugated lengthwise to increase their stiffness, with converging ends -7 7, which are riveted to triangular pieces `in the ends or points, so as to give it the requisite solidity and finish. At the pointwhere the sides commence to converge are xedthe crosspieces 8 9. f

Fig. 8 represents the cross-piece at the front end of the shuttle, which is provided with the spring 19, for holding the thread as it comes from the spindle. The thread is passed around the end of the spring to bring it to its pla-ce. The spindle is held in itsclosed position by means of anotch acting as a catch in the crosspiece 9, Fig. 6.

Fig. 9 represents a peculiar form of spindle to be used in my improved shuttle. The elastic sides are curved inwardly at a point, 20, about one-third, more or less, of the length of the slot from the hinged or pivoted end. The

spindle is pivoted inone of the solid ends of the shuttle, and from its peculiar shape forms a spring of itself, whereby it is held in place when pressed home.

The threads, as they leave the warp-beam, pass up infront of a rod, 18, Fig. 8, to the rear of a central bar, 17 5, thence up in front of 'the rod 10, through the heddles in the harnesses.

The rods 10 and 18 are attached to abar, 21, which is tted at each end on the inside of the frame, and is allowed to turn on the central bar 17 The latter is held in place by means of screws at the ends, and passing through the frame, so that the plate 21 may be turned to increaseor lessen the tension of the warp, as desired. Y Y

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the rock-shaft O, having arms M P, the shuttle-picker R, connected to the arm P, the spring attached to the upper end of the arm M, with the sliding rod I, carrying a spring, and a spring-catch pivoted on a bracket, and arranged to en gage with the lower end of the arm M, as set forth.

2. The combination, with the levers M M, of the catches L L and the sliding rods I I, operated by the slide H, the releasing devices N, and cam G, as and for the purpose set forth.

3. The combination, with the shuttle-boxes, of the adjustable spring-plates s s and mechanism, substantially as described, for vibrating said plates just prior to the throwing of the shuttle, as set forth.

4. In combination with the adjustable plates s s, the wedge d, the slides a a', and the lever c, operated by the jointed lever T, substantially as and for the purpose specified.

5. The take-up-actuating mechanism, con sisting ofthe disk n', provided with the -projecting rim r', the pivoted arms r 1^, provided with beveled ends, unyieldin g rolls 4 4, mounted in swinging holders, operating-arms p p, and crank-disk t, substantially as specified.

6. The combination of the shuttle-body, its notched cross-plate g, and the spindle, having a portion of the elastic sides curved inwardly, as shown and described.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses.
